  • Gaggia MDF mod

    HI all,
    Just wondering if anyone has the printout for grind settings for mdf stepless mod I tried to get it from the link by DSC but could not find it.
    I want to make my MDF stepless as sometime the the grind settings are too far apart.
    Any help would be appreciated.
    Thanx

    Shultzy - is it a new MDF? If so be very careful as if you modify it in the wanrranty time you will void the warranty which can be very expensive.

    DSC no longer has that mod as his issue had more to do with uneven burrs and I think he now has it back as a stepped grinder.

      Thanx Lucinda, It is a new MDF, & I think I have found the sweet spot 6 on my grinder for my silvia , I had trouble getting it right for the beans on a 25 sec shot, & I got a new La marzocco double basket , but I think I will leave the mod for now , This mornings shot was passable but this arvos shot was the best yet! Glad I took my em0480 back Personally I find the MDF 100% better.

      Cant wait for tomorrows shot,

        Ive got an MDF too and I use it with the silvia as well, but I find I need to set the grind to 3 for the standard double basket for most beans and 2 for the Decaf. With the LM basket (more coffee), I need to set it one setting coarser to get the ideal shot times. Is that normal to have the same machines but different settings reuqired?

          Yes.
          Numbers are for your own reference.
          Some manufactures dont ensure that "0" really is "0".
          So not all grinders will have an identical grind at the same number because they just slap the components together.

          However, if someone tells you to adjust "one notch more" that should still be true.

            The sunbeam is just not up to scratch when it comes to machines like Sylvia and Gaggia Classic and above.

            I tend to use 4 on my grinder for the classic, and with some beans drop it down to 3 - usually if it is a lighter roast.
            I havent tried any coarser as I get nice shots on these settings.

              Had a thought about it and I figured that since Im already puling a decent double shot at the setting of 2 and the 1 is the lowest which still might not be fine enough for a ristretto, I opened up the MDF to see if it will turn below the 1 mark and it turns out the the numbering dial thing has a stopper that stops it from going past the 1 mark but it was set quite high. Once Ive removed the number dial, turns out I can go finer yet to the point where it feels a little tight so I eased up a notch from the tight setting and set that as 1 instead. Should have noted how many clicks I went finer but my guess is I went 3 or 4 clicks finer so now it what was previously 2 is now 5 (or 6) which is more or less what everyone else seems to be getting. Will test it out with a double shot later timed to the stopwatch.

                ??? - you grind finer to make a ristretto?

                  The variation to grind setting seems common to the lower end machines like em0480, I was grinding at 1 for my silvia & sometimes-1 & even though I cleaned & checked alignment ,It still wasnt any better (on em0480)
                  Thats why I took it back. The Gaggia MDF However seems a lot more solid With brass burr holders instead of plastic ,but it comes down to quality control as other on this site have said When made in china!

                    If you like solid consider a Macap like mine.

                      Yes mate,

                      This is the recognised way to pull a Ristretto... Pulling a shot up short is not really a Ristretto, just a sub-volume standard shot. After all, that is what Ristretto means - "Restricted" - and the way to do this is to grind slightly finer to realise a shot with half the usual volume in the same 25-30 seconds shot time .

                      Cheers,
                      Mal.

                        Thanks Mal - so a dopio ristretto is a turkish?

                        ps. "ristretto" translated literally means "narrow" though in context to the coffee we make it might better translate to "cut short" or "finish early", hence my question.

                          Heres both the definition and an interesting discussion from different sources Dennis.....

                            Ive read that one before Mal and without references to back it up its an opinion.

                            Secondly, its a monologue not a discussion.
                            Dont forget too that Dennis speaks Italian.
                            His translation of ristretto should have some bearing on the argument.

                            Another point: the Definition says 50% volume, the "Discussion" says 75%.
                            No consensus.

                              Mal, I will defer to your definition or connotation of a ristretto in relation to coffee. As for the actual meaning of the word, my father spoke Italian, and my mother is Italian. With no disrespect to yourself, Id prefer to stick with what they taught me as I have more faith in them than a UK website.

                              I thought it interesting that directly under the reference to ristretto, comes...

                              "Robusta: Fine and aromatic type of coffee with igher acidity. High in caffeine and low in flavour. Grown between sea leven"

                              Two typos in just over one sentence, and I wonder if you also agree with them when they say robusta is low in flavour?

                              Sorry to take this OT shultzy. I have a little stepped conical (Isomac) and also a mazzer, which is stepless. If one notch is anything like the isomac, its quite significant. I guess if you know a way of modifying it, then it might be tempting to void the warranty, depending on how long youve had it and what youve really got to lose (or gain).
